ʻO ka lole wela kiʻekiʻe o PTFE (PTFE-coated fiberglass) he mea kūpono ia no ka hoʻomehana microwave no ka mea e hoʻouna i nā microwave me ka ʻole o ka hoʻomoʻa ʻana i ka ikehu, kū i ka 260 ° C, a he ʻano lāʻau ʻole. Hoʻohana ʻia nā moena baking microwave, nā kāʻei mea hoʻomaloʻo hoʻomaloʻo ʻoihana, nā linings reactor no ka hoʻoheheʻe kemika, a me nā ʻeke ʻeke popcorn microwave. Loaʻa nā māka FDA no ka pili ʻana i ka meaʻai.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) ʻaʻole hiki ke hoʻololi maikaʻi ʻia no ka mea he palupalu maoli ke kumu fiberglass. ʻO nā lole ʻoi aku ka lahilahi (0.08mm) ola mau haneli a hiki i nā tausani o nā paʻi; māwae koʻikoʻi (>0.25mm) ma hope o nā kakini. ʻOi aku ka maikaʻi o ka ulana satin i ka ulana maʻamau. No ka hoʻomau ʻana i ke kuʻi ʻana, e noʻonoʻo i ka kiʻiʻoniʻoni PTFE paʻa a i ʻole ka lole i hoʻokumu ʻia i ka aramid.

Hoʻohana ʻia ka lipine wela kiʻekiʻe o ka PTFE i ka ʻoihana PV ma ʻelua mau kuleana ʻokoʻa: ka hana hoʻopau (pale i ka EVA overflow adhesion ma nā laminators, solder mask) a me ka insulation lōʻihi (busbar wrap, junction box fixation). No ka hoʻohana mau ʻana i loko, pono nā lipine e hele i ka IEC 61215: 1000-2000h wela wela, UV, kaʻa uila wela (-40 ° C a +85 ° C), me ka silicone PSA a me ka emi ʻana <1%.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) i hoʻohana nui ʻia i ka paʻi textile a me ke kala ʻana no nā kāʻei paʻi wela (180-230 ° C), nā uhi pākaukau paʻi pale, nā kāʻei mesh maloʻo, nā kāʻei mīkini fusing, a me ka wili ʻōwili. Kāohi kona ʻili non-stick i ke koena o ka inika/adhesive, e hōʻemi ana i ka hoʻomaʻemaʻe downtime a hoʻomaikaʻi i ka maikaʻi o ka lole. Hiki i nā kāʻei hope ʻole ke hana mau.

ʻO ka lipine wela kiʻekiʻe o ka PTFE i hoʻopili ʻia i nā pahi hoʻopaʻa wela a me nā paʻi sila e hāʻawi i ʻehā mau kumu waiwai: pale i ka hoʻoheheʻe ʻana i ka plastic adhesion (hoʻopau i ka downtime), pale i ka make sealing pipiʻi, homogenizes wela / kaomi no nā sila mau, a hoʻemi i ka friction film. Paipai ʻia ka lipine kākoʻo fiberglass (0.13-0.25 mm) me PSA silicone (≥260°C). Lipine ʻeleʻele anti-static no nā laina kiʻekiʻe.

ʻO ka PTFE kiʻekiʻe-mehana lole (PTFE-coated fiberglass) he mea kānana kānana maikaʻi no nā kūlana koʻikoʻi: ka hoʻohemo ʻana i ka lepo (cement, waste incineration, coal boilers a hiki i 260 ° C), corrosive wai kānana (acids, alkalis, aila), meaʻai / lāʻau hoʻomaʻemaʻe sterile kānana, a me HEPA cleanroom kānana. ʻAʻole hiki ke hoʻomaʻemaʻe maʻalahi ka ʻili non-stick. Loaʻa i nā māka membrane-laminated nā hoʻokuʻu haʻahaʻa loa.

PTFE kiʻekiʻe-mehana lole mālama maikaʻi uila insulation mai -180 ° C a hiki i 260 ° C: volume resistivity>10¹³ Ω·cm ma 200 ° C, dielectric paʻa paʻa ma 2.0-2.1. Ma luna o 260 ° C, PTFE palupalu, decomposes ma luna o 327 ° C, nalowale insulation mau loa. Ma lalo o 0 ° C, hoʻomaikaʻi ka insulation akā lilo ka uhi i palupalu. Noho i loko o 260°C no ka hana pono.

Hoʻoholo nui ʻia ka waiwai o ka wai mahu o PTFE adhesive tape e ka uhi ʻana i nā hemahema (micropores, microcracks, fiber wicking) ma mua o ka PTFE intrinsic hydrophobicity. Hāʻawi ke kiʻi ʻoniʻoni PTFE maʻemaʻe WVTR wale nō. ʻO ka uhi ʻana i nā ʻāpana he nui a me nā mea hoʻopihapiha lamellar (mica, glass flakes) e hana i kahi hopena labyrinth, e hōʻemi nui ana i ka lawe ʻana i ka mahu. No ka hoʻopaʻa ʻana i ka haʻahaʻa haʻahaʻa, e hōʻike i nā uhi i hoʻopaʻa ʻia.

ʻO ka lole wela kiʻekiʻe o ka PTFE (PTFE-coated fiberglass) he mea kūpono ia no nā kāʻei conveyor meaʻai ma muli o kona kūpaʻa wela 260 ° C, -70 ° C hiki ke anuanu, non-stick surface, a me ka FDA compliance. Nā mea nui: nā umu bakena (biscuits, berena, pizza), nā mea lawe meaʻai palai, nā laina hoʻoluʻu candy, nā tunnels maloʻo, nā sila wela, a me ka ʻōwili wili. Hoʻemi i ka pau ʻole a me ka manawa hoʻomaʻemaʻe.

Hoʻoholo ʻia ke kūpaʻa ʻana o ka PTFE kiʻekiʻe-mehana adhesive lipine ma lalo o ka ukana mau loa (ʻoi aku ma 200-260 ° C) e nā kumu ʻelua: silicone PSA crosslink density (ʻoi aku ka crosslinking kiʻekiʻe e pale i ke kahe) a me ke ʻano substrate (fiberglass-reinforced PTFE e kūʻē i ke anuanu; Holo wikiwiki ka lāʻau hoʻopili ʻole i ka wela nui. ʻO nā papa pipili mānoanoa e hoʻonui i ka pilikia kolo.
